SC Intergrid reinforcement Geotextile

SC Intergrid reinforced

Interlock stiffens the aggregate

Load spread increased

Aggregate transfers load

Performance is improved

Tensioned membrane

reinforced

Geotextile anchored at edges

Load is transferred to geotextile

Geotextile and subgrade

deform

Negligible performance gain
